**The formula for percentage change is:**

**((new value – old value) / old value) x 100%**

**Here’s an example to show you how to use the calculator:**

Suppose the price of a stock increased from $50 to $60. What is the percentage change?

**Step 1:** Subtract the old value from the new value: $60 – $50 = $10.

**Step 2:** Divide the difference by the old value: $10 / $50 = 0.2.

**Step 3:** Multiply the quotient by 100%: 0.2 x 100% = 20%.

So the percentage change is 20%.

**Here’s the calculator:**

Input the old value: 50 Input the new value: 60

Result: 20%

## step-by-step guide on how to calculate percentage change:

**Step 1:** Find the difference between the new value and the old value.

**Step 2:** Divide the difference by the old value.

**Step 3:** Multiply the result by 100% to express the change as a percentage.

**Here’s an example to illustrate the steps:**

Suppose the price of a stock increased from $50 to $60. What is the percentage change?

**Step 1:** Find the difference between the new value and the old value: $60 – $50 = $10.

**Step 2:** Divide the difference by the old value: $10 / $50 = 0.2.

**Step 3:** Multiply the result by 100% to express the change as a percentage: 0.2 x 100% = 20%.

So the percentage change is 20%.

**Here’s another example:**

Suppose the price of a stock decreased from $80 to $70. What is the percentage change?

**Step 1:** Find the difference between the new value and the old value: $70 – $80 = -$10.

**Step 2:** Divide the difference by the old value: -$10 / $80 = -0.125.

**Step 3:** Multiply the result by 100% to express the change as a percentage: -0.125 x 100% = -12.5%.

So the percentage change is a decrease of 12.5%.
